Application led March 12, 1914. Serial No. 824,080.

Y molds 'forming' part of a prcssused fortorming macaroni and other tubular edible pastos and particularly relates to the mounting; of: the rcn'iowablc die pins which are centered -in the tube-'Forming openings in these plates.

l'llhe dough used in the presses is usually still' and great pressure is necessary to force lthc same through the openings in the die plates and in order to withstand this pressure the plates must be made of some `material thickness tol withstand bending especially where the openings are disposed relatively close to cach other. lVith a thick plate of this character great resistance is oiliered to the passage of the dough and where die pins are also centered in the openings the friction is materially increased.

Accordingly, it is one of the objects of the invention to provide a plate which may have a relatively large number o openings each designed so that the dough may be forced therethrough with the least possible resistance.

lV here the openings are of small cross-sectional area, the plus must be correspondingly small and yet must be so mounted that they will remain centered irrespective of the bending tendency of the dough as it is ftn'ceti through the openings, so that another object ol this invention is to provide a long thin pin so mounted in the opening that it can resist bending moments and at the same time oler the least resistance to the passage of the dough. l

Another object is to so mount the pins that they will automatically center as they are dropped into position without any special care beingf exercised in inserting the saine, and without any necessity of providing accurately milled parts to support the pins in their centered position.

A still further object of the invention is to provide a die plate which will form the sti lli1 paste into loneT tubes ot relatively small diameter compared with the edible paste tubes, now known, which will form the tubes with a thin wall havinga smooth surface on both the inner and outer sides7 and which will provide a 'wall' ci uniform thickness throughout the length of the tube.

Various other objects and advantages of the invention will be in part obvious 'from an inspection ot' the accompanying drawings and in part will bcn'iore fully set 'forth in the following description oi one 'lorin of mechanism embodying` the invention, and the invention also consists in certain newI and noi el features ci? i'zcnstruction and combination of parts hereinafter set forth and.

claimed.

In the aecompari-yingl drawings: Figure l is a side elevation ot a die pin in the course of construction and illustrating a physical embodiment ol the pin element oi' my invention; Fig. '2 is a trai'isverse sectional view which may be considered as taken through the welobed portion oli any ot' the pins shown in Figsfl to G inclusive; Fig. il is a view similar to Fig. l showing the lower-portion of the webs cut-awayto 'torni the cylindrical portion of the pin; Fi i and 5 are respectively front and side elevations oi a preferred form of die pin; Fig. is a View similar to Fig. showinga sharp edge top to the pin; Fig. 7 is a vertical sectional 1view through a portion of a die plate showing' a couple. of pms centered 1n the openings therein; Fig. 8 is a t ansvcrse section taken.

ou the line 8 8 of Fig. 7; and- Fig. -9 is a plan view looking down upon the plates shown in Figs. 7 and S.

In the drawings is shown aplate l. such as is usually `found in the bottom ot presses used 'in the manufacture of macaroni and other tubular edible pastes, which plate is designed to have ar thickness capable ot withstanding the enormous pressure t-o which these plates are subjected in machines of this character.

This plate has a plurality ot' tube-formino,` openings 2 extending tl'iercthrough, which openings are disposed as close to cach other as'possible to produce thtv maximum number ofpaste tubes with each operation ot the press. The portion of the opening 2 which first receives the dough as it is forced therethrough. that "is, the upper portion in the device illustrated, is cylindrical as shouf'n at Z3; the remaining portion is suhstainially truste-conical as shown at 4 except that the lower smaller end may merge into a relatively short annular exit i5.

\ usual with devices of Vpms are droppcdinto the openings with 'than the distance adjacent the inner ends thereof, thus vforming a wedging pocket for the pins hereinafter described.

Projecting ribs 7 extend' inwardly `from the walladjacent the bottom of these slots so as to provide a seat for the inner ends of webs which form part of these pins, and assist to transfer strains on the pins direct to the plate. f ltemovaliily positioned within the openings Z andpreferably of a length equal to the thickness of the plate .are die pins 8, which vpins have diametrically disposed relatively thin webs 9 extending outwardly from the upper portion thereof. These webs are adapted to seat' within the' slots 6 and are made as long as possible in order to brace the pin against twisting or bending strains and yet leave the cylindrical or tube-form-- ing portion ofthe pin as long as possible. The lower portions l() of the pins are preferably cylindrical but may have any/"other suitable configuration depending upon the character of the bore desired for the edible paste tubes. The webs' preferably have a cross-section substantially equal to the crosssection of the slots 6, but it is not necessary that the inclination of the sides of the webs be equal to that of the slots for any angle which will providea wedging engagement between the webs and slots in the direction of movement ofthe dough through the opening is sulieient.

' In order to reduce friction and to divide the .dough as it passes into the opening, the

` upper end of the pinsare formed into knife edges 11 by Aflattening oppposite sides of the upper portion of the pin. i

The pi.ns"'}ire preferably of bronzeor nickle steel which may be cold rolled into the form shownin Fig.' l after which a part oit' the iianges are removed to form the Vpins shown in Fig.- 3, or the en'd of suitable cylindrical rods may be insertedin rollers designed to give ythe flattened end and beveled web structure shown in Figs. t and 5 after which the outer end .may he sharpened to form the edge4 1l. I

In operation7 the plate after it has been cleaned, is positioned in thepress asis' this cliar'i'cter and tin-,

their webs positioned in the slots and resting;

er the seats provided by the ribs '7. The

'dough is forced through the cylindrical portion 3 aboutopposite sides of the flattened portion of the pin and then closes around the cylindrical portion within the tapered bore 4 to form the tubular edible paste members.

.The action of the dough passing through the openings tends to firmly seatr the pins .on the projections 7 but incase the inclination of the webs and slots are such th'atthe webs of the pins are held in wedged position olfy iitted Within 'the slots, rotaryinovement of the pins is thus prevented and any tendency of the pins to set up an oscillatory movement' 1s minimized. The long bea-rings provided` f by the edge'of the webs tend tomaintain the pins in centered position so as to provide a uniform thickness to the wall of the paste tube. This construction, using' but two wings, offersthc least possible interruj'ition to the passage of the` dough and, at the same gently tapping theirL cylindrical ends andv can be easily-cleaned when removed as there are no recesses within which the dough can collect and harden. The flat webs permit the use of rotary cleaning brush and the cylindrical portion may be readily polished' to give a clean smooth interior'to the bore `of the paste tube. v

W'hile I,have shown and described, and i have pointed out in theanneXed claims, eertain novel features of my invention, it will be understood that various omissions, substitutions and changes in' theform and details'of"the device illustrated and in its operation may be made by those skilled in the art without departing Yfrom the spirit of the invention.

Having thus described my invention, I
